I planted knockout roses last year, and due their unbelievable resilience they had been doing great until now. There are numerous shoots that have multiple small, spikey thorns instead of the usual size and some of these branches are dyng off. Is this normal? The plant is getting a little crowded by some herbs I planted in same area, and it has been well over 100 for the past 2 weeks.

Please google "Rose Rosette Disease" and find some pictures.... I'd want to make sure first that RRD is not what you're looking at; reddish stems with lots of small thorns, then death of the canes....does it look like that? If it is you've got a bigger problem than we can solve here and I'd recommend contacting your County Extension agent to make a plan of action.

If not, a picture might be helpful....

It does look like that might be the problem (rose rosette disease).

Sorry to hear that. Good luck.

This is my Meideland Rose. Would this also be Rose Rosette disease? It's growth is stunted and though it had a few blooms earlier this season, it never took off and spread as it normally does. Many of the stems look like this. I have not seen thick canes full of thorns.(Sorry about the blurry 2nd photo, but I thought it might be helpful anyway.

Thanks.

That one's tough because I can't see the degree of thornyness, but I'm inclined to think that it's not; just not deformed enough for me to call it. Again, gettin a local horticulturist to look would be your best bet to be sure.
